WRIGHT DURYEA, OF NEW YORK, N. Y.

UMBRELLA.

Specification of Letters Patent No. 12,908, dated May 22, 1855.

To all whom t may concern.'

Be it vknown that I, WRIGHT DURYEA, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Umbrellas; and I do hereby declare that the same are described and `represented in the following specifications and drawings.

'Io enable others skilled in the art to make and use my improvements I will proceed to describe their construction and operation referring to the drawings in which the same letters indicate like parts in each of the figures.

traverse in or beside each other, so that whenv the umbrella is open or spread the stetchers will hold the outer sections of the ribs to.

which they are connected in their proper places; .and at the same time, if the umbrella is closed the stretchers may be used to traverse the outer sections of the ribs in, beside the inner sections, so as to reduce its length and render it more compact for transportation when not in use.

The staff of the umbrella as represented in the drawing is made in two parts A and B, fitted to screw together at C so that when it is unscrewed the staff may be packed in a short space.

The upper portion of the part A, is made larger and hollow as represented at D, to form a-receptacle for a cloth case or cover, to protect the umbrella when not in use. The upper end of the tube D is closed by the ferrule or point E, which is tted to screw onto the tube D as represented. The collar F is fitted to turn freely on the tube D, just below the end of the ferrule E. This collar F is made in the usual form with scores for the ends of the ribs, and a groove around it for the wire which fastens the ends of the ribs to it and upon which they vibrate. The ribs are each made in two parts Gr and I-I; the part G being fastened to the collar F, and provided with a clasp I at the opposite end, which clasp is fastened to it, and

so constructed as to allow the outer part of g.

rmly to the end of I-I .and provided with a i.. 'L

projection K, to which the end of the stretchers L are fastened witha rivet so as to vibrate freely, to open the ribs and spread the umbrella, or to traverse the part H when necessary. The outer ends of the parts II are perforated for the purpose'of' securing the covering properly.

The stretchers L, L, may be made in the form represented or otherwise, and fastened to the slide M, in the usual manner; which slide M is made in the usual form and fitted to traverse on the stad A and B, the former being provided with a spring catch N to support the slide when the umbrella is spread, and the latter with the catch O to hold the slide when the umbrella is closed.

The frame of the umbrella is represented as spread in the drawing, and it may be closed by pressing in the catch N and drawing the slide M down the staff and onto the catch O. If it is desirable to render it more compact to carry or put in a trunk, press in the spring O, and push up the slide, surrounding the stretchers with the hand at the same time, to prevent them from spreading, so as to slide the outer parts of the ribs I-I, along by the sides of the parts G, thereby reducing the length of the ribs nearly one half; and if the top of the staff is turned down, the covering of the umbrella will fall down around the ribs, and may be pressed against them, so as to occupy but a small space; the part B may be unscrewed, also the ferrule E so that the whole can be packed in a short space with great convenience.

When it is wanted for use the parts which have been unscrewed may be screwed on again, and the slide M drawn down, so as to run out the ribs and a slight rotary motion given to the staff so as to throw 0H the ribs, whenthe slide may be pushed up to spread them as represented in the drawing, and when so spread the stretchers L L hold the outer parts of the ribs I-I I-I out in a proper position to spread the covering in a proper manner.

Although I have represented the staff as being screwed together, I contemplate that it may be connected with a link so as to fold like a common parasol staff, and provided' With a slide to hold it straight; the staff being reduced in size Where the last mentioned slidetraverses upon it, so that the slide Which operates the stretchers can pass freely over it. Also that a female screw may be made in the collar F and a male screw on a stai that may be used for a cane When it is not Wanted to operate the umbrella. And further that the part G of the rib may be made tubular and the part H fitted to slide into it instead of sliding by the side as heretofore described.

What I claim as my improvement- In umbrellas With ribs made in tWo parts,
